摘      要：For the development of mid-infrared fiber-optical elements, one needs tight-stable, flexible materials that are transparent within this spectral band. Solid solutions of silver and monadic thallium halides prove to be the most suitable crystalline media for these needs. We study the light stability variation of high-purity AgCl1-xBrx （0 ≤ x ≤ 1） and Ag1-xTlxBr1-xIx （0 ≤ x ≤ 0.05） crystals by measuring the optical transmission change as func- tions of the composition and UV exposure time. The former is executed in a broad spectral range from 6500 - 350 cm^-1, within which we choose three wavelengths to trace the transmission change. For thallimn- monoiodide-containing samples, an effect is observed that we assumed to be translucence.
